THlLL-COUPLING.

$PECIPICATION forming part of Letters Patent No. 485,426, dated November 1, 1892.

Application filed June 8, 1892- Serial No. 435,951. (No model.)

To all whom it may concern:

Be it known that I, JACOB K. PFLEIGER, a citizen of the United States, residing at Richland Centre, in the county of Bucks and State of Pennsylvania, hat e invented certain new and useful Improvements in Anti-Battling Thill-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in anti-rattlin g thill-couplings; and the object of the invention is to improve, simplify, and cheapen the cost of construction of this character or class of devices, and at the same time provide a device which will be expeditious and effective in the operation of coupling and uncoupling the thills or shafts to and from the clip-jaws or extensions of the clips of the device, as occasion requires.

WVith these ends in view the invention consists in the novel construction and combination of the several parts, as will be hereinafter more fully described in detail, and particularly pointed out in the appended claim.

In the accompanying drawings, to which reference is had and which fully illustrate my invention, Figure 1 is a side elevation of the device embodying my improvements, and Fig. 2 is a top or plan view of the same.

Similar letters of reference indicate corresponding parts in both the figures.

Referring to the drawings, A indicates an axle, and B B are clips secured thereto by nuts or any suitable fastening means, and embracing or surrounding the axle, both of which-that is, the axle and clipsin this example are of the usual, but may, if desired, be of any suitable or preferred form. Centrally secured to the under side of the clipbars is a stud or projection I), which is clearly shown in Fig. 1 of the drawings, the purposes and functions of which will be hereinafter explained.

0 indicates suitable operating-springs, the rear ends of which are secured to the threaded depending ends of the clips by means of nuts 0, the forward or free ends of said springs having secured to them blocks D, by means of screws 01 or other analogous fastenings. These blocks D are transversely perforated, as

at E. Through these perforations are passed wire loops or locking-latches F, which are passed over and loosely embrace the jaws or extensions of the clips, serving to couple and uncouple a pair of shafts or thills GG to and from the jaws or extensions of the clips B B. Pivotally secured to the upwardly-extending curvilinear ends of the jaws or extensions F are suitable flaps or cap-pieces H H, having formed upon their upper and outer surfaces and parallel with each other transverse grooves h h for the reception of the free or upper ends of the locking-latches or loops F, which look in place to the jaws or extensions F of the clips or release at will therefrom the rear ends of the thills or shafts G G, which are loosely fitted in hearings in the upper horizontal portion of the jaws or extensions F of the clips B B. The loops or lookinglatches F F when in their normal position lock and hold securely together both the flaps and jaws or extensions F of the clips B B, as shown clearly in full lines in coupled position and in dotted lines when in uncoupled position in Fig. 1 of the drawings. The front portions of these flaps are curved to conform to the curvatures of the clips, so that they may fit closely and snugly against the clips. The studs or projections 12, which are centrally secured to the under side of the clip-bars, give a resilience to the springs 0 when the forward or free ends of the springs are raised, and

consequently force upwardly the locking latches or loops F, which releases the flaps H H and uncouples the shafts or thills from the clip jaws or extensions, this operation of coupling and uncoupling, as before men tione'd, be-

ing shown in full and dotted lines in Fig. 1 ofv the drawings. The springs O effectually prevent all rattling or tendency to rattle of the shafts or thills. The force of the tension of the springs, being great, draws downwardly with sufficient pressure upon the flaps to keep them firmly in position and prevent any play whatever of the rear ends of the shafts in their bearings to cause rattling when the vehicle is in motion.

My invention is simple in its construction, not easily gotten out of order, durable, and cheap to manufacture.

From the foregoing description, taken in connection with the accompanying drawings,

the operation of my device will be obvious, latches or loops F, springs 0, blocks D, and and further description thereof is herein shafts or thills G G, all operated substandeemed unnecessary. tially as herein described, and for the pur- Having thus described my invention, what I poses set forth. 5 claim as new, and desire to secure by Letters In testimony whereof Iafitix mysignature in 20 Patent, is- I presence of two witnesses.
